Specification of Letters Patent.

To all whom it may concern.-

Be it known that I, HANS THEODORE HAN- SEN, a citizen of the United States, residin at Wauwatosa, county of Milwaukee, an State of Wisconsin, have invented new and useful Improvements in Motor-Driven Vehicles, of which the following is a specification.

My invention relates to improvements in motordriven vehicles, and pertains especially to that class of such vehicles in which the power is applied to the steering-wheels through a universal joint in the plane of the wheel and of the pivot of its oscillation.

The object of my invention is to provide means whereby the joint of the driving connections may be located exterior to that of the supporting connections, thereby enabling me to provide a rigid stationa central support extending through the hu of the wheel and to provide driving connections of great strength and durability by obviating the necessity of the extreme economy of space, which is required where the driving connections are centrally located.

In the' following description reference is had to the accompanying drawings, in which Figure 1 is a view of the inner side of a vehicle-wheel embodying m invention, showingwthe steering-rod and riving-arms of the sprocket-wheelin cross-section on line a: a: of Fig. 2. Fig. 2 is a view of the Wheel with the lower half partially broken away and showthe upper half in axial section. Fig. 3 is in a detail top view of the connections between the steering mechanism and the wheel.

Like parts are identified b the same reference characters throughout t e several views. 1 is a stationary axle-shaft provided with a yoke 2, within which the wheel is mounted,

and an annular projection 3, upon which the sprocket-wheel; islnounted. An oscillatory rin 5 is mounted on vertical pivot-studs 6, an the wheel-hub '7 is mounted upon this ring 5 with interposed antifriction balls or rollers at Sand 9.

The spokes 11 ofthe wheel are connected with the outer end of the hub 7 at 12 and are dished or offset inwardly at 13, the rim 14 and tire 15'being ill the central plane of the ring 5. Arms 17 progect inward y from two of the spokes of the w eel on opposite sides of the center, and a knuckle-ring 18 is pivoted to these arms. The knuckle-ring 18 is provided with inwardly-projecting pivot-studs 20 at right angles. to the points of pivotal connection .with the arms 17, and arms 21, V

a mounted on said transmitted to the worm-shaft 26 from any suitable source of power, manual or otherwise, through a rotary steering rod or shaft 28, bevel-pinions 29 and 30, shaft 31, and

gear-wheels 32 and 33, the latter being fast on the worm-shaft 26. The steering-rod 28 extends through the annular projection 3 on the shaft 1. V

A suitable brake-shoe may be conveniently supported from the yoke 2 by a rod 35 and spring 36, against the tension of which the brake-shoe is actuated by a lever 37. The brake-shoe is preferably swiveled to the rod 35, whereby it is permitted to adjust itself 'to the wheel.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a vehicle of the described class, the combination of a central fixed axle-shaft provided with vertically-extending pivot-studs an oscillatory ring mounted on said pivotstuds; a wheel having its hub rotatably ring; and driving mechanism having universa -joint connection with the wheel exterior to the hub and substantially in the plane of the wheel-rimn 2. In a vehicle of the described class, the combination of a centrally-pivoted wheelv support; a wheel-hub rotatable on said support; a Wheelconnected with the outerend of the hub and dished inwardly; and driving mechanism-having universaLj oint connection with the wheel between the hub and rim.

3. In a vehicle of the described class, the combination of a central pivoted wheel-support; a wheel-hub rotatable on said support;

a wheel connected with the outer end of the hub and dished inwardly; and driving mechanism having universal-j oint connection with the wheel between the hub and the rim; together with means for steering said wheel.

'4. In avehicle of the described class, the combination of a wheel having spokes connected with the outer end of the hub and off- 25 7. have set inwardly at an intermediate point; a v,

pivotally connected-on opposite sides with two of the spokes; substantially in the plane of the wheel-rim; and a driving member-hav- 5 ing arms pivotally connected withfsaid ring on opposite sides and at right angles to the line ofwheel connection.

5. In a vehicle of the described class the xleeshaft; an-

combination of a central fixed a vertical pivot bearings; a

- mounted on said ring; and driving mechanism'having universal-'qoint connection with the wheel, between said ring'and theirim of :5 the wheel.

6. In a vehicle of thedescribed class, the.

I combination of a central fixed axle shaft; an

oscillatory-ring supported from the shaft-by vertical '-pivot-bear1ngs; a wheel rotatably ism having universal-joint connection wit the wheel between said ring and the-rim of. the wheel; together with means mounted on I said rings class,--the v the stationarfilshaft, for oseillatin 'cle of the'describe ism havin 'HIIiVOlSB. joint connection with oscillatory ring supported-from the'shaft-by wheel rotatably' mounted on said ring; and'driving meehanfor transmitting motion to oscillate the ring through said se ment. 1 '35 8. a vehic e of the described class the combination of a' central fixed axle-shaft; an

oscillatory ring supported from the'shaft by vertical pivotbearings mounted on-said rin anddriv'ing mechano ism having- .univers a wheel rotatably 4 v-joint connection with. the wheel.between-said ring and'the rim of thewheel; together with means for oscillate ingsaid ring.
